QML property list empty when accessed from C++

SmokeOnTheWater

Good afternoon,

How can a qml property list be accessed from C++ side?

I think an example should make things clear:
@
// MyItem.qml
Rectangle
{
// some properties
}

// MyComponent.qml,
CppComponent // available through qmlRegisterType<CMyComponent>("myComponents", 1, 0, "CppComponent");
{
width: 100
height: 62

property list<MyItem> myItems;

}
@

@
// Usage.qml
Rectangle
{
width: 100
height: 62

MyComponent
{
    myItems: // <--- the property list gets filled here
    [
        MyItem
        {
            x: 100
            y: interpolator.rotationCenter.y
            width: 150
            height: 200
        },

        MyItem
        {
            x: 100
            y: interpolator.rotationCenter.y
            width: 150
            height: 200
        }
    ]
}

}
@

The big question is: how can the property list be accessed from C++
side?

My stupid approach was:
@
QQmlListProperty<QQuickItem> mis = this->property("maskItems").value<QQmlListProperty<QQuickItem> >();
@

because
@
this->property("maskItems").typeName();
@

returns "QQmlListProperty<MyItem_QMLTYPE_0>"

But the list is empty...

I also tried a QList<QQuickItem *>, QVariantList and some other stupid things
I cannot remember anymore but it's the same all the time:
no items are contained in the list when it is accessed from C++ side

What's wrong here?

Thank you in advance,
Martin
